+# This script allows you to install Asterisk into a subdirectory of 
+# your source distribution and run it from there.
+#
+# Example usage:
+#
+#   contrib/scripts/live_ast conf-file # optionally. and now edit live/live.conf
+#   # edit live/live.conf
+#   contrib/scripts/live_ast configure
+#   make
+#   contrib/scripts/live_ast install
+#   contrib/scripts/live_ast samples
+#   contrib/scripts/live_ast run
+#   contrib/scripts/live_ast run -r
+#   ./live/asterisk -r                 # Same as run -r
+#
+# A standard debugging cycle of a code in a module:
+#
+#   # edit apps/app_skel.c
+#   contrib/scripts/live_ast install
+#   contrib/scripts/live_ast run -r 
+#   # and in the CLI:
+#   module unload app_skel.so
+#   module load app_skel.so
+#
+# If you have external scripts that run asterisk, use the script 
+# live/asterisk that is generated by the 'samples' command. In this case you
+# should probably also rem-out the line 'astvarrundir' and maybe also 
+# 'astetcdir' in live/etc/asterisk.conf .
+#
+####################### Begin Samples
+# optional environment variables. Set those in live/live.conf or in 
+# your envirnment.
+#
+# LIVE_AST_LIBPRI_PATH:
+# To use a libpri SVN directory (without running 'make install': make include
+# a symlink to the current directory:
+#   ln -s . /path/to/checkout/of/libpri/include
+# Be sure to run there 'make'. Then set in live.conf:
+#LIVE_AST_LIBPRI_PATH="/path/to/checkout/of/libpri"
+#
+# LIVE_AST_ZAPTEL_PATH:
+# Likewise, the same trick can be used to build vs. a local copy of zaptel:
+#   ln -s /path/to/checkout/of/zaptel/include .
+#   ln -s /path/to/checkout/of/zaptel/zaptel .
+#LIVE_AST_ZAPTEL_PATH="/path/to/checkout/of/zaptel"
+#
+#LIVE_AST_DAHDI_PATH="/path/to/dahdi-linux/dir"
+#LIVE_AST_DAHDITOOLS_PATH="/path/to/dahdi-tools/dir"
+#
+# Another alternative for Zaptel is to use the live_zap script included 
+# with the Zaptel distribution. The following should work after you used 
+# './live_zap install' or even with a copy generated with 
+# './live_zap rsync' . '/apth/to/zaptel' is the directory containing the 
+# live/ subdirectory:
+# 
+#LIVE_AST_ZAPLIVE_PATH="/path/to/zaptel"
+#
+# LIVE_AST_LD_PATH_EXTRA: 
+# space-separated or colon-separated directories to add to 
+# LD_LIBRARY_PATH. It is added before any existing components of 
+# LD_LIBRARY_PATH.
+#LIVE_AST_LD_PATH_EXTRA="$HOME/lib:$HOME/libtest /opt/testapp"
+#
+# LIVE_AST_CONFIGURE_PARAMS:
+# Extra parameters to pass to ./configure.
+#LIVE_AST_CONFIGURE_PARAMS="--enable-dev-mode"
+#
+# LIVE_AST_FORCE_DEF_CONF:
+# If set to a non-empty value, always regenerate menuselect config.
+# This avoids emenselect's nag about "configuration has changed" that 
+# happens occasionally after an svn update.
+#LIVE_AST_FORCE_DEF_CONF=yes
+#
+# LIVE_AST_BRISTUFFED_LIBPRI
+# A hack to use the second, "bristuffed" copy of libpri that exists
+# e.g. in the Debian libpri-dev package. If set to a non-empty value, 
+# live_ast will edit makeopts to use that second copy after ./configure
+# is run.
+#LIVE_AST_BRISTUFFED_LIBPRI=yes
+#
+# LIVE_AST_FOR_SYSTEM
+# When generating asterisk.conf, use most components from the installed 
+# system. Also provide a sane var-run directory for those of us who want 
+# to do the right thing and run asterisk as non-root.
+#LIVE_AST_FOR_SYSTEM=yes
